The present invention is concerned with the provision of an electricallyoperated window cleaning device which may be used Ywith absolute safetyby a workman, and which will prevent the possibility of a window cleanerfalling out of a window, inasmuch as the device may be used Ion anywindow from the inside of a room.,

A further object of the invention is to provide a window cleaningldeviceofsim le, practical construction, w i l1 may be rea ilymanipulated across the igger face ofja conventional type of slidingashto effect-simul-l taneous cleaning of both'the inner and outer facesof the window pane.

Further objects of the invention 'are to provide a window cleaner ofrugged, durable construction, which/may be manufactured and operatedwith lcomparative economy, and which will befextreinely expeditious inuse, inasmuch. as an entire window may be cleaned in the..timefordinarily taken to clean one side thereof. l

More specifically the invention in its preferred embodiment includes anelectromagnetic device against which, a cleaning element is held andmoved over the interior face of a window pane. (lo-operating with theinside cleaning element is a similar element at the outside of the paneretained in place by the magnet, and' -lirmly pressed against the windowpane b the magnetic force. The outer cleaner Wi ythus be caused totravel over the outer face of the window pane, and follow every movementof the in ner cleaner which is mounted on the magnet, and both faces ofthe pane will be cleaned simultaneously.

With the above noted and other objects in view, the invention consistsincertain novel features of construction and combinations andarrangements of parts, as will be more fully hereinafter set forth andpointed out in the claim. The invention may be more fully understoodfrom the following description in connection with the accompanyingdrawings, wherein- Fig. 1 is a perspective view illustrating the mannerof use of'a window cleaner embody- .in the present invention.

` iig. 2 is a sectional window of Fig. 1.

Fig. 3 is a view partly in sideA elevation lment, and that the cleaningreadily manipulated over-the inner face of detail through theandprincipally in longitudinal section through a cleaning apparatusembodying the present invention.

Fig. 4 is a plan view of one of the cleaning pads. v Fig. 5 is an endview of the magnetic operating device. l

In the' drawings I have shown a window frame mountlng a conventionaltype' of sliding sash 11, the window pane. 12 of which is to' becleaned. vThe cleaning apparatus includes an energizing coillvenclrcling a soft iron core 14 upon w 'ch is mounted a plate 15. Thecore is preferably covered with some suitable -material 16, and may beused as a handle for moving the plate 15 over the inner surface of A'flexible electrical conductor 17 connects the energizin coil to ansuitable'sourcc of current, and ecurrent may be convenientl regulated bya conventional type of push the window pane 12. A

utton or other switch 18 f mounted in a switch casing 19 at one -end ofow through the coil the coil. Preferably the coil is mounted upon aspool 13, and one head ofthe spool is secured to the plate 15 in anysuitable manner, the other end of the spool bearing the switch casing.

v One form of cl indicated in Fig. A4, an as shown consists of a flatbag 20 of cloth or other suitable material filled with steel wool 21 orequivalent v soft paramagnetic l material. ablyr the bag is formed ateach side with a central opening 22, so that the'steel wool may restdirectly againstthe end of the core 14 which lies flush with the plate15. When the magnet is energized it will be evident that it will attractthe magnetizable cleaning eleelement may be the-window pane. At the sametime, a similar cleaning element disposed upon the exterior face ofVthe'window will be attracted by the magnet and manipulation of theelectromagnet will cause both cleaning elements to act simultaneouslyVupon opposite sides of the window pane.

j In order to prevent accidental loss of the outer cleaning element, itis referablyat-v tached by a string or other exible device to the'magnet Various changes and alterations might be Prefermade in thegeneral form and arrangement of parts described without departing fromthe invention. Hence I do not Wish to limit myself to the details setforth, but shall consider myself at liberty to make such changes andalterations as fairly fall within the s irit and scope of the appendedclaim.

I c aim:

A window cleaning apparatus including an electromagnet ada ted to be`manually ma 10 ace lby manipulation of the magnet, the 15 cleaningelements comprising ads of steel wool ,covered by polishmlg clot s.
